I have little experience soldering components to circuit boards and for
those who are similarly lacking in experience, here is a list of the =
things
that I did not know and had to find out in order to put the components =
in to
the correct circuit position on the circuit boards.
I have to warn you that I have not tested the circuit, so can not as yet
confirm whether I am correct.
All the resistors came pre identified and stuck to a sheet of paper all =
you
have to do is pull it off the paper and stick it in the correct location =
on
the circuit board. All of the colour codes are also listed under each
resistor and all of them matched the description given you can solder =
them
in any way round, although the guy I spoke to said it was good form to =
have
all the gold bands going the same way as it makes it easier to read them =
if
you are checking the circuit later.
I then used the descriptions on the digikey part's list
ftp://diy-efi.org/pub/diy_efi/project_files/diy_wb1/WBO2DigikeyBOM.txt =
to
identify the remaining components.
I thought I knew what a capacitor looks like, but there are several
different types as follows:
The first surprise was that the LED isn't just a light but it's also a =
diode
and has to go in the correct way round, close inspection will show the =
short
leg lines up with a flat on the rim of the LED and this aligns to the =
double
bar end on the circuit board graphic.
D1,D6,D7,D10 these are the smallest copper colour and are aligned
black end to the double lined graphic.
D3 big black one, needed to ream the holes to make it fit.
D4,D9 these are the larger copper colour
D8 LM 385 black three legs cant go wrong
D11,D5 LM 431 black three legs cant go wrong
Next surprise is the capacitors - lots of different types.
For the ones that have a long and a short leg, the long leg is +=20
